Recent geophysical and geochemical observations, together with experimental and theoretical studies, have greatly advanced our understanding of the Earth's deep interior. Nevertheless, key questions, such as the heterogeneous structure of the silicate mantle, the composition of light elements in the iron core, and the mechanisms of Earth's formation and evolution, remain unresolved. Meanwhile, collaborative efforts between Earth sciences and materials sciences are providing new insights into the physical and chemical behavior of deep Earth materials, including core-mantle interaction and their coevolution.
This joint session aims to create an interdisciplinary forum that integrates cutting-edge results from geophysics, geochemistry, mineral physics, computational science, and materials science to deepen our understanding of Earth and planetary interiors. We particularly welcome studies employing innovative methods and technologies such as high-resolution electron microscopy, high-precision paleomagnetic measurements, geophysical and geochemical observations, geoneutrino detection, large-scale multiscale simulations of mantle convection and the geodynamo, high-pressure mineral physics, and machine-learning techniques for predicting material properties.
By promoting active exchange among participants and combining expertise across disciplines, this session seeks to stimulate new research directions and strengthen cross-field collaborations. Presentations related to the development of the Japanese Deep Earth and Planetary Research Group (SEDI-J) are also encouraged. The session is sponsored by the Commission on Physics of Minerals, International Mineralogical Association (CPM-IMA).
